ktest.pl: Add shell commands to variables
Allow variables to execute shell commands. Note, these are processed when
they are first seen while parsing the config file. This is useful if you
have the same config file used for multiple hosts (as they may be in a git

HOSTNAME := ${shell hostname}
DEFAULTS IF "${HOSTNAME}" == "frodo"
